The aim of the research was to evaluate the characteristics of thermal environment and thermal comfort in the Dry Double floors Hydronic Ondol System. Physical indoor thermal environments (the floor surface temperature, the vertical temperature, etc.) and skin temperature have especially been measured. Physical features conditions, sensation, thermal comfort, humidity sensation, comfort of body were investigated for the survey. As a result, (1) During the operation of the boiler (12 hour), the average indoor temperature is appeared to be $21.6^{\circ}C$. The floor surface temperature showed peak value of $31.4{\sim}40.6^{\circ}C$ after 8hours 30minutes after the start-point of the heating. The vertical difference of temperature was turned out to be not uniform. (2) While the skin temperature showed a narrow distribution of temperature in the Dry Double floors Hydronic Ondol system. (3) The response to thermal comfort which people felt was satisfactory, and most of them felt dry during the test.

Since the apartment was built by Korea National Housing Cooperation in 1961, the amount of its supply has been increased greatly, especially from the late 70's. Recently there are many ongoing studies regarding sustainable construction apartment in Korea, one of the research is developing sustainable apartment that has longer life cycle. Also according as life's quality of residents is upgrading, complain for impact noise and plumbing system noise from upstair or downstair are increasing more and more. To solve this complains, government established impact noise standard as lightweight impact noise of 58dB, heavyweight impact noise of 50dB and presented standard floor system or recognition floor system to satisfy this impact noise standard. So in this study, the aim is to develop dry ondol access floor system for sustainable apartment which have pleasant and quiet life environment.
